Hi John! Thanks so much for your comments: I am glad that some applications in ED106 are helpful! I too have worked with short teaching time frames and found that integrating a few brief, on-point activities right into the presentation helps to maximize skill acquisition without taking a lot of time. As a side note, you may have received a forum repsonse from me in error regarding working with silence when no student volunteers an answer to a question. Let me apologize, I mixed up two different forum responses, perhaps it might be helpful anyway. Thanks again!! Jay ED106
